• What is the cause and solution for SAP error message CNV_20100518 - Reset of confirmation not possible any more ?

  The SAP error message CNV_20100518: Reset of confirmation not possible any more typically occurs in the context of data migration or conversion processes, particularly when using the SAP S/4HANA Migration Cockpit or similar tools. This error indicates that a confirmation (such as a goods movement or a production order confirmation) cannot be reset due to certain constraints or conditions in the system.
  Causes:
  
  Status of the Document: The document (e.g., production order, delivery) may be in a status that does not allow for a reset. For example, if the document has already been settled or if it is in a completed state, the system may prevent any further changes.
  Data Integrity Constraints: There may be data integrity rules in place that prevent the reset of confirmations once certain conditions are met.
  Custom Logic or Enhancements: Custom code or enhancements in the system may impose additional restrictions on the ability to reset confirmations.
  Locking Issues: The document may be locked by another process or user, preventing the reset operation.
  
  Solutions:
  
  Check Document Status: Review the status of the document associated with the confirmation. If it is in a completed or settled state, you may need to reverse or cancel the document before attempting to reset the confirmation.
  Use Transaction Codes: Depending on the context, you may need to use specific transaction codes (like CO13 for production orders) to check the status and make necessary adjustments.
  Consult with Functional Team: If you are unsure about the status or the implications of resetting a confirmation, consult with your SAP functional team or a consultant who specializes in the relevant module (e.g., MM, PP).
  Review Custom Code: If there are custom enhancements in your system, review them to see if they are affecting the ability to reset confirmations.
  Check for Locks: Use transaction SM12 to check for any locks on the document and resolve them if necessary.
